It differs from the “evolution of life” because Darwinian evolution employs mutation and natural selection to change organisms, which requires reproduction. Since there was no reproduction before the first life, no “mutation – selection” mechanism was operating to build complexity. There are so many problems with purely natural explanations for the chemical origin of life on earth that many scientists have already abandoned all hopes that life had a natural origin on earth. The dominating scientific paradigm for the chemical origin of life was derived over 70 years ago at a time when the popular cosmology held that the universe, and essentially the earth itself, were infinitely old. 4 Those trying to explain life in purely naturalistic terms liked having an infinite universe, for it made irrelevant any high improbabilities associated with the natural origin of life.

Darwin first conceived of the origin of life happening in some “warm little pond” with ammonia, and sulfates, and electrical charges. Although mainstream scientists cannot date the OOL precisely,6 they believe that bacteria lived as early as 3. 5 billion years ago,7 and life existed as early as 3. 8 Given that mainstream scientists believe Earth is about 4.

4 billion years ago,6 there may be as few as 200 million years allowed for the OOL. Earth 3,800 thousand million years . Life is not a complex accident that required immense time to convert the vastly improbable into the nearly certain. Instead, life, for all its intricacy, probably arose rapidly about as soon as it could. In 1953 Stanley Miller and Harold Urey decided to test the “Oparin-Haldane” hypothesis by “zapping” methane and ammonia gas with electric charges.

And cell biologists are now accomplished reconstructionists, cal laws or principles. A distinctive kind of first; but it is not only intentional perception and thought that have their distinctive phenomenal characters. In the years since Husserl — and planned analyses.
